Using multiple outside IPs on ADSL (PPPoE) connection

[Matej Šerc]

Hi,

until now we had one outside IP address and used FreeBSD machine to do
NAT and run some mail and webserver for our needs. Few days ago we got
a /30 subnet (netmask 255.255.255.252) and now, when I connect to ISP,
I get only first IP of the subnet. Of course, while it's available, I
would like to have some services "listening" on other IP addresses as
well. I have searched a lot and I have found a guy, asking just the
same as I am (http://groups.google.com/groups?hl=sl&lr=&threadm=6261e7aa.0409030400.107b2db2%40posting.google.com&rnum=15&prev=/groups%3Fq%3D%2522freebsd%2522%2B%252B%2B%2522subnet%2522%2B%252B%2B%2522pppoe%2522%26start%3D10%26hl%3Dsl%26lr%3D%26selm%3D6261e7aa.0409030400.107b2db2%2540posting.google.com%26rnum%3D15),
but got no appropriate answer.

Configuration file for ppp (/etc/ppp/ppp.conf) is at follows:

default:
  enable lqr
  set lqrperiod 15
  disable ipv6cp
connection:
  set device PPPoE:rl0
  set authname username
  set authkey pass
  nat enable yes
  nat same_ports yes
  nat use_sockets yes
  set dial
  set login
  set ifaddr first_ip_of_subnet 10.0.0.2/0 255.255.255.252
  add default HISADDR

Now, as also in that post from google, tun0 has only that IP
address... I also tried to define second_ip_of_subnet with subnet mask
255.255.255.255 to rl0, but still that second IP isn't pingable from
outside world.

Thanks everyone for help:)
